Hotpoint wf540 washing machine flashing lights / fault

Hi all
I have a 2 year old Hotpoint WF540, everything was going fine then the flashing lights started.The machine goes through the wash phase and then when it gets to the rinse/spin cycle the machine will stop and the start & mini load lights will flash thats it will not go any further. This fault seems to only be on high spin cycle ie 1400 machine works ok and goes through full cycle start to finish on 800 spin (I have not tried it on any other spin cycles other than 800/1400)
I have so far cleaned all the pipework checked for blockages, changed pump (I had a spare) but I still have the same problem
Can anyone help please?

Hi Again!
Well Rocks1 I hope you are watching this post maybe you can help me again? I thought I would check the bushes on the motor before I ordered a new board. Well I took them off and had a look everything looked fine so I put them back, but when I started the washing machine up to check it the machine started lasted about 20 seconds and then stopped bringing up another fault (third light down on my machine) f02 light 3 motor, jammed/ tacho I thought well get another board as I have tried everything else. I bought a refurbished board from emwelec as you suggested it arrived today only for me to fit it to find I still have the fault f02 light 3 motor, jammed/ tacho. If only I had just left it alone!!!!! and done what you said in the first place. what have I done! please help!

Thanks for your reply Rocks,
I think I may have to check the motor brushes again why dont I just stick to fixing cars!!!
I will try to have another look tonight but it is getting late and its time to read the bed time stories to my girls. If I dont get back to you I will post a reply tomorrow night when I have checked the brushes. once again THANK YOU.

Well I have checked the motor brushes again, fired the old machine up and hey presto lights one and two are now flashing communication error! it wont be long before I have had all the error codes available why did I say to the missus dont worry I can fix it!
